- Open-source “Human-Brain-Rat” bidirectional BCI project was shared, including a GitHub repository (https://github.com/Unlimited-Research-Cooperative/Human-Brain-Rat) and a diagram illustrating two-way brain-computer communication between human and rat.  
- DIY sodium-silicate (“waterglass”) synthesis from household materials was explored: participants reacted kitty-litter silica gel with NaOH, discussed optimal Si:Na molar ratios, noted iron contamination giving an amber color, and compared costs with commercial sodium silicate.  
- Rapid refractory-foam experiments combined sodium silicate with shaving foam, lime, perlite, and clay; the mix set to a waxy solid within hours and withstood ~1000 °C propane-flame exposure before becoming crumbly, suggesting potential low-cost moldable insulation.  
- Practical glass-working discussion covered Prince Rupert drops, fiber-optic arrays, and the feasibility of small-scale glassblowing using only a torch and vermiculite insulation.  
- Links to cutting-edge reproductive bioengineering were posted: bioengineered uterine tissue enabling pregnancy in rats (PMID 27068301) and ex-vivo culture of shark fetuses (PMC10530027), plus an egg-freezing guide.
